SEAT ATTACHMENT FOR MOTOR-CYCLES.

Specification of Letters Patent.

Patented May 28,1912.

Application filed January 17, 1911. Serial No. 603,116.

To all whom it may concern:

- Be it known that we, FRANK R. CovnY and CHAnLns FnANous HoAe, citizensof the United States, residing at Riverside, in the county of Riversideand State of California, have invented new and useful' Improvements inSeat Attachments for Motor Cycles, of which the following is aspecification,

The invention relates to a seat attachment for motor cycles or bicycles,and more particularly to the class of tandem attachments for motorcycles, bicycles or the like.

The primary object of the invention is the provision of an attachment ofthis character in which one or more persons may mount and ride a motorcycle or bicycle, without discomfort or being subjected to jolts or jarsincident thereto on the travel of the same.

Another object of the invention is the provision of a device of thischaracter in which a motor cycle, bicycle or the like may be readily andconveniently converted to a tandem, thereby affording seating capacityfor several riders upon the same.

A further object of the invention is the provision of an attachment ofthis character which is easily and quickly'mounted upon the frame of amotor cycle 'or bicycle, whereby the same may be converted into a tandemto enable two riders to be mounted thereon for carriage from one pointto another.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereunto appended. 1

I11 the drawings: Figure 1 is a side elevation of a motor cycle with anattachment constructed in accordance with the inven tion mountedthereon. Fig. 2 is a rear elevation thereof. Fig. 3 is a perspectiveView of the attachment removed from the cycle.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring to the drawings by numerals, 5 designates generally the mainframe of the motor cycle or bicycle which is of the ordinary well-knownconstruction, and in the rear fork 6 of which is 'rotatably mounted therear supporting wheel 7 the latter being journaled on a rear axle 8which is secured in the rear fork 6 in the usual wellknown manner.Connected to the frame and the rear axle 8 is a tandem attachment orsupplemental seat support, which will be hereinafter more fullydescribed. This tandem or seat support comprises an inverted fork 9,from the medial portion of which rises a stud or stem 10, to which isswiveled one end of a resilient bracket or arm 11, the opposite endbeing formed with an upturned perforated ear 12, with which is pivotallconnected a split collar or yoke 13, the latter belng adapted to embracethe vertical tube or seat post of the main frame 5 of the motor cycle orbicycle' Spaced from the ends of the fork 9 and secured to the innerface thereof are inwardly projecting offset bearing lugs 14, the freeends of which beng provided with suitable apertures receivlng the rearaxle 8, the lugs being connected to the latter by means of the usualnuts carried thereby.

Mounted upon the free ends of the fork 9 are yieldable foot rests,comprising arms 15, the same being connected medially thereto to thefork 9 by means of pivots 16, and these arms are outturned to providefoot stlrrups 17 in which are journaled rollers 18, providing treads forthe feet of a person mounted upon the tandem attachment.

Pivotally connected to the arms 15 are guide rods 19, the latter beingupwardly projected and loosely working through eyes 20 formed on theends of rearwardly extending brackets 21 fixed to the fork 9 contiguousthe bearing ears 12. Surrounding these guide rods 19 are coiledexpansion springs 22, each having one end working against an adjustablenut 23 threaded on the guide rods 19, while its opposite end bearsagainst the eye 20 of the bracket 21, so as to tension the stirrups andpermit the same to yield when pressure is applied thereto by the foot ofa person. Threaded on the upper ends of the guide rods 19 are adjustablenuts 24, the latter normally resting against the eyes 20 of the brackets21, the nuts being adapted to regulate the tension of the springs 22surrounding the said guide rods, so as to increase or decrease the resistance of the springs when foot pressure is applied to the stirrups.

Mounted upon the stud or stem 10 is a riders seat 25 of the usual orordinary type, the same being adapted to be occupied by a rider whenmounted upon -the attachment. When the rider is occupying the seat, hisfeet are engaged in the stirrups, thus assuring a comfortable and steadymount upon the attachment.

What is claimed is:

1. An attachment of the class described, comprising an inverted forkhaving a stem medially thereof, a resilient arm connected with the stemand with the seat post of a bicycle frame, lugs formed on the fork andadapted for engagement with the rear axle of said frame, pivotalstirrups carried at the free ends of the fork, and means for yieldinglyholding the stirrups in position on their pivots.

2. An attachment of the class described, comprising a fork, meansconnecting it with the axle of a motor cycle, means connecting the forkwith the frame of such motor cycle, stirrups pivotally connected withthe free ends of the fork and having tread rollers, brackets fixed tothe fork and projecting rearwardly therefrom, guide rods pivotallyconnected to the stirrups and working through the brackets, andsprings'cooperating with the guide rods for tensioning the stirrups.

8. An attachment of the class described, comprising a fork, meansconnecting it with the axle of a motor cycle, means connecting the forkwith the frame of such motor cycle, stirrups pivotally connected withthe free ends of the fork and having'tread rollers, brackets fixed tothe fork and projecting rearwardly therefrom, guide rods pivotallyconnected to the stirrups and working through the brackets, springscarried by the guide rods and acting upon the stirrups for holding themunder tension, and means for regulating the tension of the springs.

In testimony whereof We aflix our signatures in presence of twowitnesses.
